Relative abundances of bacterial taxa across all 324 samples. Circular stacked bar chart showing the bacterial relative abundances of all the samples in the study cohort (n=324), divided based on parity – no previous pregnancies or deliveries (nulliparous) (n=188) and one or more previous deliveries (multiparous) (n=136). The samples have been ordered based on two criteria 1) gestational age in weeks, increasing clockwise (outer band) and 2) within each gestational age bracket, whether one of the top 3 bacteria were the most abundant (>50% composition), ordered clockwise from None, to Gardnerella vaginalis, Lactobacillus iners, and Lactobacillus crispatus dominant samples.
